Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the MAC comparison in tcp-ao does not use a constant time, potentially leading to timing...

PT-2026-39045

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A timing attack issue exists in the TCP Authentication Option TCP-AO implementation. The Message Authentication Code MAC comparison was not performed in constant-time, which could allow ...

PT-2026-39044

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A timing attack is possible because Message Authentication Codes MACs are not compared in constant time. This allows an attacker to potentially deduce information by measuring the time t...

GHSA-53HJ-R94P-8C8F Kanidm has non-constant-time comparison of OAuth2 client_secret

Summary The kanidmd OAuth2 token-exchange /oauth2/token and token-introspection /oauth2/token/introspect endpoints compare the supplied clientsecret against the stored secret using Rust's PartialEq on String, which short-circuits on the first mismatching byte. This produces an observable timing...

GHSA-248H-974Q-XRC2 axonflow-sdk-java: Webhook signing-key (HMAC-SHA256) not exposed by SDK type, preventing signature verification

Summary The AxonFlow SDK's WebhookSubscription or equivalent type did not expose the HMAC-SHA256 signing key returned by the platform's CreateWebhook endpoint. Without access to the secret through the typed SDK API, callers had no path to verify the X-AxonFlow-Signature header on incoming webhook...
